Applicatio filed January 18. 1907. Serial No. 352.946

To all whom it may concern:

Be it known that we, \VILLIAM H.v REIS- NEn, Snwnm. C. Swan'rz, and\VILLIAM T. IIAMILTON, citizens of the United States, re. siding atlIagerstown, county of Washington, and State. of Maryland, have inventedcertain new and useful Improvements in Machines for ApplyingBinding-Qtrips to Books;

and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to apparatus for applying or allixing bindimstrips, of paper, muslin or the like, to the backs of books or similararticles and has for its object to provide a greatly simplified andhighly ellicicnt mechanism for accomplishing the object aforesaid.

To this end the invention comprises means ,for supporting and feedingthe books to be bound, in partly opened position while the strip ofpaper, muslin or the like, which has been coated with adhesive isapplied and seoured to the backs of the books, as said books, togetherwith the strip are passed ,throughicoacting feed rollers, one of whichis provided with a convex periphery engaging the inner side of the bookat the fold and the other having a concave periphery engaging the backof the book and serving to fold and for'ce the pasted strip into contactwith the book back. I or the purpose of accurately severing the bindingstrip at the rear edge of the book the mechanism is provided with astrip-cutting knife, operated from the driving mechanism, but heldinoperative, at all times, except when a book is just leaving the These,and other novel features of the invention, will be more particularly setforth in the following specification and claims, and are-illustrated inthe accompanying drawings in which--- A Figure 'l is an end elevation ofa complete machine; Fig. 2 is a plan view thereof; Fig.

3 is a side elevation with one-hall of the book-supporting tableremoved, to show the relative arrangement of the operating mechanism;Fig. 4 is a detail view of the knife actuating cam and stop mechanism;Fig. is anenlarged elevation of the strip-cutting knife and its housing;Fig. 6 1s a view, corresponding generally to Fig. 3, showing a modifiedform of drive for the feed rollers; Fig. 7 is an enlarged detail view ofthe trip for controlling the operation of the knife; Fig. 8 is a detailshowing the mode of securing one member of the strip carrying roll inposition.

Referring to the drawings, 1 indicates th e base of the machine whichmay be of any suitable shape or size and is illustratedmerelyconventionally in the present '=in stance. Supported by suitablestandai'ds 3, on said base is a table or frame upon which the books areplaced, and over which ,they are moved during the operation of applyingthe strips to the backs thereof. It has been found that if the books areonly partially opened so as to present the backs thereof as an invertedV to the mechanism for applying the binding strip to the back, themechanism for eilecting the operation may be greatly simplified and theoperation itself materially expedited. To this end the table 01' supportconsists of two transversely inclined plates 22, preferably of metalhaving the form of an inverted V, to support the bookin partly openedrelation and present the back thereof to-the strip allixing iced wheels.

Mounted adjacent to the apex of the inverted \l-shaped table are themain feed rollers 6 and S which serve not only to pass the books throughthe machine but, also, to suitahl y crease or fold the adhesive stripand apply the same to the back of the partially opened book. The feedroller 8 which is mounted below the table projects slightly above theapex of the table, through a suitable opening therein and the peripheryof said feed roller is convexed or tapered to con--' form generally tothe contour-of the table sides 2-2. The periphery of Miller 6 is pro- "iled with a corresponding if shaped con cavity, so that the peripheriesof the twotical standards 15, secured to the base 1 and the.other end isattached to a helical spring 10, connected at its upper end to one ofthe standards 3. Said spring 10 therefore tends to throw roller 8 intoclose engagement with roller 6, but permits the said roller to movedownward when a book is passed between the two rollers 6 and 8. In orderto adjust the tension on the roller 8, the set screw 11 is tappedthrough the angular end of the bracket 9 and engages with its upper enda stationary abutment, such, for exam ile, as the under side of standard3, so that r y adjusting said screw the tension of the spring and,consequently, the bearing contact between the feed rollers 6 and 8 mayhe nicely adjusted. Mounted upon the axis of the swinging bracket 9 is asecond feed roller 16 provided with a generally convex eriphery of thesame character as that of roll clr 8', and, if desired, the convexsurface of said rollers may be knurled or roughened to increase thedriving friction and insure an even steady feed of the books. Roller 16is positively driven by means of a sprocket wheel 19, fixed to the axisthereof, which is engaged by a sprocket chain 17, cooperating wit adriving sprocket wheel 20, mounted upon a countershaft 21, which, inturn, is driven through sprocket wheel 18, chain 22, sprocket wheel 23,pinion 24, and gear 25, the latter being fixed to the shaftCoiiperatirig with the roller 16, which projects through a suitableopening-in the apex of the table, is a feed roller 28, having a convexperiphery of the same general character as that of roller 6, and saidrollers 16 and 28 cobperate to continue the feeding and pastingoperation with respect to the books, as

the latter are delivered-from the main feed rollers 6 and 8. The upperauxiliary feed roller 28 is mounted in swinging links .27 which arepivoted to a bracket 26 forming a lateral extension from the mainbracket or standard 4. In order to hold roller 28-in i'irm, yetyielding, contact with roller 16, springs 29 mounted upon the bracket 26bear with their free ends upon the swinging 2727. In order to preventthe ro ler 28 from swinging too far downward, a fixed link 30, attachedto the bracket 26, has a pin and slot engagement, at its lower end withone of the swinging links 27, which permits the roller 28 to move up anddown within the limits defined by the slot'in said link 30.

Mounted immediately in the rear of the feed rollers 6 and 8 is astrip-cutting knife 31 having a lower cuttin edge notched to conform tothe angular re ation of the table sides 2-2. The knife 31 is mounted ina guide head forming the end of bracket 25 and is held in position bymeans of removable face plates 26. Normally the knife isheld in retracted position by a spring 33 secured to the hooked end of the rod 32mounted on the therefrom and engaging the top 0 links s'insai headofbracket 26 It is intended that knife 81 shall be operated to sever thebinding strip close up to the rear edge of the book as the latter leavesthe feed rollers 6 and 8 and to accomplish this purpose there is mountedupon shaft 5 a cam 39 which engages roller 38 connected to a rock shaft35 mounted in brackets 36 secured to main bracket 4,.said rock shaft 35having an arm 34 rojecting f the knife to force the latter downward ascam 39 moves rock shaft 35. It is essential, of

course, thatthe knife be not operated to sever the strip until the bookpasses outof engagement with feed rollers 6 and 8 andmeans are thereforeprovided for holding the knife actuating means inoperative until passageof the book from between said rollers 6 and 8 permits the knifeoperating cam to exercise its function. .To effect this the cam 39 ismounted upon a disk 41 loosely mounted upon shaft 5, but adapted to bero tated with shaft 45, except when positively restrained, by means of afriction disk 42, preferably of leather or the like, which engages theface of cam disk 41, and is positively attached to the correspondingface of a drive disk 40, keyed to and positively driven from shaft 5.

effective friction clutch when said-disk 41 is held in contact with theintermediate friction member 42 by means of helical spring 43,

surroundin the shaft 5 and bearing between the hub of isk 41 and anadjustable collar 44 screwed upon shaft 5, The'pressure exerted byspring 43 between'cam disk 41 and the friction member 42 of disk 40 maybe regulated by the adjustable collar 44. Unless disk 41 is positivelyrestrained, the frictional engagement between the same and disk 40 willcause said disk 41 to rotate so that cam 39 will actuate rock shaft 35and reciprocate knife 31 once for each rotation of shaft 5. To preventcam disk 41 beingrotated except'at the proper time, it is provided onone face with a pin 47. adapted to engage a detent or stop 48 which ispivoted to the bracket 4, Said detent 48 is connected by a short link 49with an arm 50 projecting from the end of a short rock shaft 51 mountedin brackets52, 53, secured to the standard 4. Secured to the rock shaft51 is anlarm 55 carrying at its end a roller 56 which normally occupiesa slight depression 57 in the table 2, a spiral spring 54 surroundingshaft 51 and engaging arm 55 and bracket 52, respectively, normallytending to force said trip arm 55 toward the tab e and simultaneouslytomove said stop or detent 48 out' of the path of movement of pin 47.When, however, a book is passed between the rollers 6 and 8, roller 56enga ing one of the covers of the book will'be li ted, thereby movingsaid rock shaft 51 against the tension of spring 54, and

Said disks 40 and 41 with the swinging detent 48 outward until its upperend hes directly in the path of movement of pin 47 on disk 41 whicharrests the rotatory movement of said disk 41 and prevents cam 31further operating the knife actuating mechanism. This relation of theparts is maintained as long as the book lies under sive books, to whichthe strip is to be applied,

' it will, of course, be desirable to prevent the knife being operatedfor the reason that, if it trip arm 55.

which hook supports the trip 'were operated, it would necessarily cutoft short len ths of the stri which would be wasted; 0 hold thetherefore, When'no book is between rollers 6 and 8 and'under roller 56,there is provided on the hub of disk 41 a cam 46 which engages the sideof stop or detent 48 moving the same outward, rocking shaft 51 andelevating trip arm 55. As said arm 55 is elevated by this means, a pin56 projecting laterally from the end of said rod, adjacent the roller56,. engages a hook or latch 58 which is pivoted to an arm 60 rigidlysecured to bracket 26,

arm and prevents its return into engagement with the table. The pivotedhook 58 is engaged by-a springfi secured to arm 60 which normally tendsto move the lower end of said hook into engagement with a slight grooveor depression in the table 2 and also tends to force the hook intoengagement with pin 56 when said hook is lifted by the elevation of 'hensaid hook 538 is engaged by the pin 56" to support the trip arm 55, itslower end lies substantially in the plane of table-top 2 and when a bookis passed between rollers 6 and 8 it strikes the lower end of hook 58and swings said-hook to disengage it from pin 56, thereby permittingtrip lever 55 to fall until the roller 56 engages theside or cover ofthe book. It will thus be seen that the knife is actuated but once foreach book that is passed through the machine and then only when the bookpasses out of enwhich-actuates knife 31.

gageincnt with roller 56 on trip arm 55, which permits the latter tofall and move detent 46 out of the path of movement of pin 47 to permitcatn disk 41 to operate the rock shaft 35 immediately after the knifehas been actuated,.cam 46 moves dottent 48 outward to throw trip arm 55upward and lock the same in this position by means of hook or latch Thestripmis fed from a roll mounted upon a suitable reel journalcd upon apintle 66 mounted in a standard 81 secured to the base 1'. The reelconsists of a main hub rnife inoperative,

82 provided with cross-arms, and an auxiliary hub 8 1-. The main hub isheld in position on the pint-1e St) by means of a brake spring 83 whichengages a peripheral groove in one end of the hub. The removable hub 84with its cross arms is detachably secured to the pintlc by means ofspring-pressed pin 85 located in the hub and adapted to engage acircumferential groove 86 near the end of the pintle. By exercising aslight pull axially on said hub 84 the pin 85 is forced outwardlyand-said hub may be slipped off, and. conversely, by forcing the hub 84in the opposite direction the pin 85 will be retracted until it comesinto registry with grooves 86 when it will lock the hub in position. Itwill be apparent that the ready removability of the hub 84 makes it easyto renew a roll of binding strip. I

From the reel the strip is led over a guide roll 70 mounted upon apintle 71 secured to the base 1 and confined in position by cross pins 72. Thence the strip passes over a pastor roll 7 4 which is journaled ina paste box 73; from 74 the strip passes under a second guide roll 75,thence upward to a sta' tionary guide, comprising a generallycylindrical sleeve 67 mounted upon a bracket arm 69 and provided at itsouter end with a gener ally helical guide flange 68 which directs thestrip downward and also gives it the necessary twist to produce com letereversal of the strip to bring the pasted side downward as it passesunder the final guide roll 65 mounted u on a pintle 66 secured tobracket 53. In or( er to give the strip a preliminary set before it isengaged by the feed rollers 6, a guide 62 of an inverted \l-shape is suported by a rigid arm 61, immediately in rout of and below feed roller6. A generally similar guide 64 is located iimncdiately behind therollers 6 and S and just ahead of the knife 31.

In order to secure an even distribution of paste or other adhesive byroll 74, there is provided a scraper 76 pivotally mounted in the forwardpart of the paste box 7 3 and provided with a counter-weight 78 whichtends to force the scraper against the periphery of roll 74. Theproximity of scraper 76 to the periphery of the roll may be nicelyadjusted by means of a set screw 79 in the arm of counter-weight 78,which set screw bears against the end of the box.

Power is imparted to the machine by way of pulley 7 which drives shaft 5and countershaft 21 continuously, thereby causing the feed rollers 6 and8, 16 and 28, to rotate. Normally and until the first book is fedbetween the rollers 6 and 8 far enough to lift latch 58 and roller 56away from the table, the knife operating mechanism is held inoperative.'l he books are )artially opened and laid face downward on the inclinedtable sections, so that the backs lie along the ridge formed by themeeting of the table sections.

2 feed roller 6 t The binding stri having been laid over the severalguide rol s, the pasting wheel and between the feed rollers 6 and 8, thefirst book is shoved forward untilit engages the forward feed rollers 6and 8. The latter yields sufficiently to accommodate the thickness ofthe book, but, nevertheless, exerts suflicient pressure to feed the bookforward and, inasmuch as the back of the latter engages the under or andalso passes out ofengagement with roller 56, the latter falls into thenotch or recess 57 permitting the spring -54 tomove stop or detent 48out of the path of movement of pin 47, thereby permitting. disk 41 to bedriven by disk 40 and to positively rock the shaft 35 and advance knife31 to sever the stri' immediately at the rear edge of the boo detent 48forward and elevates triparm 55 until the pin 56 engages latch 58 whichrevents furtherv again locks disk 41 and actuation ofthe knife untianother book is fed into the machine.

It will be ap arent that instead of making he driving member the lowerfeed roller 8 may be made the driver. Such an arrangement is illustratedin Fig.v 6, wherein the lower feed roller 8 is positively driven bysprocket and chain gearing 56-7 from the shaft of feed roller 16.
